Corp. Ref. No. 037109
Date Sept. 1990
SUBJECT: RATTLING/CLICKING NOISE IN FLYWHEEL AREA WHILE ENGINE IS RUNNING
MODELS AFFECTED: 1991 BROUGHAMS
Some 1991 Broughams equipped with the 5.0L engine (VIN code E) may exhibit a rattling or clicking noise coming from the flywheel area while the engine is running. This noise may be more apparent when the engine is cold.
This noise may be caused by the interference between the torque converter cover and the starter. The starter may push the converter cover to contact the flywheel producing the noise.
To repair this condition use the following procedure:
1. Remove the torque converter cover.
Figure 1 - Trimming of Material on Cover:
2. Using utility knife or equivalent tool, trim away 5 mm (.20") of material on cover as indicated by the dash line. Refer to Figure 1.
3. Reinstall the torque converter cover.
4. Inspect for interference to verify that sufficient material has been removed.
NOTE: If the torque converter cover already has the 7 mm (2.80") opening, it will not be necessary to modify the cover.
